An Explicit Discrete-Time Large- and Small-Signal Modeling of the Dual Active Bridge DC-DC Converter Based on the Time Scale Methodology

The conventional method to model a dc-dc converter is by averaging its state variable over a switching period. However, due to the dc-ac-dc structure of the dual active bridge converter (DABC), the average value of the inductor current over a switching cycle is zero. Therefore, the conventional meth...
